Stable Isotopes for Biologics

The National Institute of Standards and Technology (NIST) is seeking proposals to perform stable‑isotope analysis services supporting biologic products. The work will likely involve the preparation, measurement, and interpretation of isotope ratios in complex biological matrices to support product development, quality control, or regulatory submissions. Because the solicitation only references “See attached” for details, the exact scope, deliverables, and technical specifications are not visible in the provided text. • Service focus: stable‑isotope measurement for biologics (e.g., therapeutic proteins, vaccines). • Expected expertise: high‑precision isotope ratio mass spectrometry, sample preparation for biologics, data analysis, and reporting in compliance with FDA/EMA guidelines. • Potential deliverables: analytical reports, raw data sets, method validation documentation, and consultation on interpretation. • Likely contract type: fixed‑price or cost‑plus research services. • No explicit timeline, budget, or submission requirements are available in the excerpt.
